2.) Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is red, and C is yellow. In the reactions in which they participate, they are reduced to A-, B-, and C- ions respectively, all of which are colorless. When a solution of A is mixed with one containing B- ions, the color changes from green to red.
Which species is oxidized?
Which is reduced?
3.) When a solution of A is mixed with one containing C- ions, the color remains green.
Is A a better oxidizing agent than B?
Is A a better oxidizing agent than C?
4.) Arrange A, B, and C in order of increasing strengths as oxidizing agents.
